- Title
“ . . . .6 Seconds loud, undifferentiated noise [recording ends]” A History of Cockpit Recording in Transport Safety.

- Abstract
Cockpit voice and data recorders, originally developed between 1930 and 1950 to monitor the testing of experimental aircraft, have become the mainstay of aviation forensic science. Today’s solid-state recorders store thousands of perimeters, few of which will ever be used in accident analysis. Most help schedule maintenance, anticipate failures in avionics, and optimize system performance. However, voice recordings continue to provide a view into the human element of an event that data alone – no matter how much is retrieved - cannot see. This can make the difference between knowing only what happened, and finding the all-important answer as to why it happened. Since 1995, recorders have also become the norm for rail and bus transport – and the private automobile, as most new cars are now equipped with a downloadable Event Data Recorder (EDR) linked to the car’s airbag system. With the advent of dashboard voice-actuated command systems, auto recording is probably just around the corner, if it hasn’t already started.
